West Bank ended DST
by Steffen Thorsen Sept. 30, 2011

Sept. 30, 2011

West Bank did end Daylight Saving Time this morning/midnight (2011-09-30 00:00). So West Bank and Gaza now have the same time again. Many sources, including: http://www.maannews.net/eng/ViewDetails.aspx?ID=424808 "BETHLEHEM (Ma'an) -- The Palestinian Authority announced late Thursday that clocks will be set back one hour on Friday at midnight, the official PA news agency Wafa reported." Our small summary: http://www.timeanddate.com/news/time/westbank-ends-dst-2011.html Best regards, Steffen Thorsen - timeanddate.com

Re: Information wanted #1: time zone names in Belarus, Russia, and Ukraine

Ukraine has resolution #8330 that was passed on 2011-09-20, where the wording is "the second time zone with the addition of one hour". http://w1.c1.rada.gov.ua/pls/zweb_n/webproc4_1?id=&pf3511=40036 http://translate.google.com/translate?hl=en&ie=UTF8&prev=_t&sl=auto&tl=en&u… The resolution also abrogates two prior resolutions. #15-12 (dated 1990) - the one establishing the year-round "second time zone without the addition of one hour": http://zakon.nau.ua/doc/?code=15-12 http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=U… and #2176-12 (dated 1992) - the one establishing daylight saving time: http://zakon.nau.ua/doc/?code=2176-12 http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=U…

missing extension rules
by Zefram Sept. 28, 2011

Sept. 28, 2011

I've found a problem with the tzfiles for Africa/Cairo and America/Argentina/San_Luis. They both show a last known transition in the recent past, and surprisingly lack a POSIX-TZ-format rule for extending the zone into the future. My tzfile parser treats a zone with no extension rule as being undefined for any time following the last explicit transition, so for these two zones it reckons the zone is undefined for the present. In the source files they're each currently configured to observe a set of DST rules, and the ruleset has no transitions configured for the future. So for the present and foreseeable future, the zone is on a constant offset with no DST transitions. The tzfile reflects that by showing no transitions from the present up to 2038 (where zic always fills in a complete set of expected transitions). It should be trivial to also reflect that foreseen behaviour in a POSIX-TZ string that just gives a fixed offset and no DST rule. For example, Africa/Cairo should clearly have "EET-2". I could have a go at a zic patch to fix this, if the regular zic hackers would like to work that way. For America/Argentina/San_Luis there's an extra wrinkle: the last known transition is a transition *to* DST. Its fixed-offset foreseeable behaviour therefore has a fixed is_dst=1, which is moderately silly. It's arguable that in this case it would be incorrect to give a "WARST3" extension rule, because that doesn't accurately express the DST status. Since that DST transition was in 2009, it's also a good bet that they haven't stayed continuously on DST since then, of course. -zefram

new links for time zone page on twinsun
by Steve Allen Sept. 28, 2011

Sept. 28, 2011

I suggest a few additions to the links on the twinsun time zone page http://www.twinsun.com/tz/tz-link.htm Starting last December the ITU-R has provided free online access to their recommendations. These are visible at http://www.itu.int/pub/R-REC It is a major change from the previous restrictions on ITU-R documents. This includes the time and frequency recommendations http://www.itu.int/rec/R-REC-TF/en some of which are now suppressed but which describe the history of the usage and nomenclature. In particular it has the current and two previous versions of ITU-R TF.460 which is the document that describes radio broadcast time signals and UTC. http://www.itu.int/rec/R-REC-TF.460/en The earlier versions document the connections between UTC and GMT. There are many other possibly relevant sources, but these have been deemed particularly important and they are the basis for the inputs that go to the zoneinfo database and code. -- Steve Allen <sla(a)ucolick.org> WGS-84 (GPS) UCO/Lick Observatory--ISB Natural Sciences II, Room 165 Lat +36.99855 1156 High Street Voice: +1 831 459 3046 Lng -122.06015 Santa Cruz, CA 95064 http://www.ucolick.org/~sla/ Hgt +250 m

Information wanted #1: time zone names in Belarus, Russia, and Ukraine
by Arthur David Olson Sept. 27, 2011

Sept. 27, 2011

I'm asking for information to use in specifying time zone abbreviations for Belarus, Russia, and Ukraine. For all three I can use: 1. References to government documents that specify time zone names or abbreviations. 2. References to government documents that specify whether current time is considered to be "standard" time or "saving" time. 3. References indicating what time zone names or abbreviations are actually in use in the areas. 4. References indicating whether people in the areas consider themselves to be on "standard" or "saving" time. We do have this year's Decree #725... http://www.government.ru/gov/results/16355/print/ ...for Russia; if translate.google.com is correct, Moscow is on "Eastern Standard Time" with most other zones being "Eastern Standard Time plus n hours" and one zone being "Eastern Standard Time minus 1 hour." --ado

Information wanted #2: Russian Decree #725 vs. tzdata2011k
by Arthur David Olson Sept. 27, 2011

Sept. 27, 2011

There are five places where this year's Russian Government Decree #725... http://www.government.ru/gov/results/16355/print/ ...and tzdata2011k differ on what current time is: Place Decree #725 tzdata2011k Notes Bulunskij MSK+6 MSK+7 covered by Asia/Vladivostok Tomponskij MSK+6 MSK+7 covered by Asia/Vladivostok Ust'-Majskij MSK+6 MSK+7 covered by Asia/Vladivostok Ojmyakonskij MSK+7 MSK+8 covered by Asia/Magadan Sakhalin MSK+8 MSK+7 already separate--Asia/Sakhalin Did a change occur in these areas in 2011 and, if so, when? Or is tzdata2011k wrong? Decree #725 indicates that it abrogates Decree #23 of January 8, 1992 (among other things abrogated); is the abrogated decree available online? Thanks for any help folks can provide. --ado

RE: UTC as basis for time legislation
by Paul_Koning＠Dell.com Sept. 26, 2011

Sept. 26, 2011

>> ... But other than that, if you say GMT you mean the same time as if >> you say UTC. > >Uh... you like waving red flags in front of bulls, don't you? Or maybe >walking up to a bee hive and whacking it with a short stick is your >idea of a good time. :) Ouch. My apologies to the hornets. I did some reading and I think I now understand some of the subtleties involved. Let me restate the point I should have made and hopefully not disturb another beehive. The tzdata uses an approximation of the subtle details of timekeeping. With those approximations, GMT and UTC end up being described both as having a constant 0 offset. So if country A says its legal time is an hour ahead of GMT and B says they are an hour ahead of UTC, those are technically different statements. However, to the approximation of tzdata, the outcome is the same: both country A and B would be shown in the tzdata file as having an offset of 60 minutes. Is that correct? paul

The file... ftp://elsie.nci.nih.gov/pub/tzdata2011k.tar.gz ...is now available; this reflects changes circulated last week on the time zone mailing list. I plan to send out two requests for information about Belarus, Russia, and Ukraine within a day. --ado
